breech 'loading-firearms, of the dropfdown type, iwherein the barrelsare superposed, that is arranged one above the other.

' It has for its objectto provide an elicient percussion mechanism,simple in construction vand readily` attached to the breech. Thismechanism is provided with hammers axially disposed 'with respecty tothe guns, an arrangement which is in contradiction with what has beenhitherto proposed in tirearms of this type. Y

AIt will be readilyV grasped that ,the ar`v rangementv is symmetricalkwithrespect to an axis located midway of the barrel axes',

` that is, also midway ofthe rod axes. The

strength of the vpercussion is equal for both guns. Therej is noyoblique part, dilicult to manufacture and liable to cause unduefrictionand wear.A V l Y The frame, as described, also supports the twoloading levers8 and 8' pivoted at 9 Aand 9' respectively andactingrdirectlyon heads 5 and 5. Levers ,8: and 8 are actuatedbyintermediate levers y10 and 10' pivoted at 11 and 11' and lwhich receivethe action of the loadingrodslQ and 12'.

It will. readily be" grasped thatthe partsreferenced'4-, .5, 6, -etc.r.w. 85' l breech ing faces of thecooperating parts (for instance, teeth 14-15 or 14-15) are easilymachined with a true gear tooth profile, which is also a materialadvantage.

The parts associated with one hammer are quite independent from thoseassociated with the other. The mechanism described may functionseparately from the arm, which permits easily adjusting its parts.

This mechanism, with its covers, is adapted to be fixed to the breech ina particular manner. The breech (Figs. 4 to 7) has no tail portion(contrary to` the known arrangements) and it terminates at the rear by avertical way 2O (Fig. 5) into which the mechanism is upwardly slid asshown in Figs. 13 and l114. The upper-. face of frame 1 is provided witha projecting part 21, square in horizontal section, which fitsf into asquare hole 22 (Figs. 4, 5 and `6) provided in the breech at the upperend of way 20.

The fixation is `perfected in two ways:

The trigger-guard 23 fits into a depression 24 in the lower face of thebreech, where it is fixed by screws 25 (Fig. 13) screwed into holes 26(Fig. 6). This trigger-guard is also fixed to the frame 1 of themechanism by screws 27 (Fig. 13) and it is provided with an upwardlyprojecting portion 28 which fits at the rear of a downwardly projectingpart 29 provided `on frame l, as it is clearly understood from Fig. 14.

A separate tail portion 30 (Figs. 8 and 9) is fixed to the breech byscrews 31 (Figs. 13 and 14), screwed into holes 32 of `the breech (Fig.`4), and this portion is also fixed to the frame 1 of the mechanism by ascrew 33.

It will be` readily understood that by such a fixation, the breech,mechanism, tail portion and trigger-guard form a rigid block' as if itwere made in one piece.

A very material advantage of such an arrangement is that the rearportion of the breech is easily machined, without having to forge it.

Of course, the arrangement described requires `a bolt or other barrellocking device, wholly exterior tothe breech or percussion mechanism.

The bolt illustrated comprises a part sliding on the upper face of thebreech. The

`latter (Fig. 7) is provided with a IT-shaped projection 34 cooperatingwith a correspondingly T-shaped sliding bolt 35 (Figs. 10, 13 and 14)which, when pushed towards the barrels, projects over the same and locksthem in position. This bolt is loaded by springs 36 (Fig. 14) acting onfingers 37 depending `from the same, said springs and fingers beinghoused into `ways 38 provided in the (Fig. 7). 39 (Fig. 10) pivoted at40 on the bolt itself and provided with a radial slit 41 cooperat- It isactuatedby a lever ing with a pin (not shown) fixed into a hole 43 ofthe breech (Fig. 4). When lever 39 is rotated in the direction of arrow44 (Fig. 10), the bolt is pulled toward the rear and frees the barrels.

A device is provided whereby the bolt is retained in its rear position(position of Fig. 14) when the barrels are dropped, to avoid the rearface of the same striking and rubbing against the front face of the boltwhen the breech is again closed. This device comprises a small springloaded piston 45 (Fig. 14), housed in a vertical blind hole 46 of thebreech (Figs. 4 and 14) and terminating upwardly into a tooth 47 bywhich bolt 35 is retained, as shown in Fig. 14. When the breech is`closed, a lateral projection 48 fixed to the barrels (or integral withthe same) strikes tooth `4.7 and lowers piston 45, whereby bolt 35 isfreed and closes under the action of springs 36 (Fig. 1 3).

Figs. 11 and `12 illustrate a modification in which two bolts are used.These bolts 49 and 49 are disposed laterally of the breech and eachisloaded by a spring 36. The actuating lever 50 is pivoted at lion thebreech and ityacts directly on bolt 49. This lever 50 also actuatesanlintermediate lever` 52 pivoted at 53 `on thebreech, and which in turnactuates bolt 49. Of course,

with this modification, it is necessary toprovide two retaining pistons`45, one on each side of the barrels.

I claim: i

In a double-barrelled, drop-down, breech-loading firearm, a framehaving a vertical median partition in the vertical plane of the barrels,and a percussion device on each side of the partition aindsymmetriucally positioned with respectthereto, each percussion device comprisinga rectilinearly movable hammer, a spring bearing on the hammer, strikingmeans acting directly on the primer and rigidly connected to the head ofthe hammer, and means carried by the frame for retaining `and releasingthe hammer. f 1` 2.

3. The device set forthin claim 1, in which the strikingmeans vis fixedsubstantially at the center of gravity ofthe head of the hammer. j 3 A yj 4. The device set forth in claim `1,` in which the spring bearing onthe hammer,

5. The device setforth in claim 1, including means for locking thebarrels to the breech, said "means comprising a bolt slid- `portions 4ofthe 7 able on the breech, a finger depending from the bolt, a springpositioned in a groove in the breech and acting on the depending finger,and an operating lever pivoted on the bolt and acting on a portion ofthe breech.

6. The device set forth in claim 1, in which the hammer has a longtravel and is acted on by a long and strong spring.

7. The device set forth in claim l, including a tail portion xed to thebreech and a trigger guard, the percussion'A device being movable in thebreech, the fixation of the percussion device being obtained by thetrigger guard and tail portion. Y
